ROCKER SIDE BEARING.

Specification of Letters Patent.

Patented Mar. 14:, 1916.

Application filed October 22, 1914. Serial No. 868,012.

To all whom it may concern:

Be it known that I, CALVIN B. PATCH, a citizen of the United States,residing at Glenellyn, in the county of Dupage and State of Illinois,have invented a certain new and useful Improvement in Rocker SideBearings, of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

This invention relates to improvements in rocker side bearings.

The object of the invention is to provide a side bearing for railwaycars which consists of few parts, that may be cheaply and easilymanufactured and assembled and which will provide a bearing efiicient inoperation.

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices, asherein shown, described or claimed. And although I herein show anddescribe in detail one form of my improvements, yet I do not wish to beconfined to the details shown and described, inasmuch as I am aware thatvarious changes and modifications may be made in the arrange ment anddetails of the parts Without departing from the spirit of the inventionand I contemplate all such changes and modifications as fall within thescope of the claim forming a part hereof.

In the drawing, Figure 1 is an elevational View of a body and truckbolster of a railway car, showing my improvements in connectiontherewith. Fig. 2- is an enlarged vertical sectional view takensubstantially on the line 22 of Fig. l and showing more particularly theimproved side bearing, and Fig. 3 is a similar sectional "iew takensubstantially on the line 33 of Fig. 2.

In said drawing, 10 denotes the truck bolster, which is swiveled in theusual manner to the body bolster 11 and, as shown, the body bolster isprovided with an integral bearing plate 12 on each side of the king pin.Cooperable with each bearing plate 12, is one of my improved rockerbearwith a journal bearing 17, which bearings are open at the top topermit the insertion of the journals 18-18 formed integrally.

with the rocker C. The rocker C isprovided with a curved bearing surface19 and converging flat sides 2020, the latter being adapted to cooperatewith the flattened heads 21 of the rivets 15 to limit the rock ingmovement as indicated thegdotted lines in Fig. 2. with an axiallyextending opening 322 and also with a radially arranged-opening 23,

The rocker *is, providedsee Fig. 3. On opposite'sides'of the opening 23and near the top thereof are pro-- vided short slots 2424: in which isadapted to be seated a pin 25 inserted-through a loop 26 formed on theupper end of aspring 27, the lower end of the spring 27 being providedwith a similar loop 26 through which is inserted another pin 29,

which is seated in suitable recesses 30pm vided in the base 1'; of thesupporting bracket.

It is believed that the operation of my improved device will be apparentfrom the preceding description, and it will be noted that the parts maybe readily assembled and disassembled, since the rocker is held to thebearing bracket B by the spring 27, which is attached to the rocker andthe bracket at its opposite ends by the removable'pins 25 and 29. Thespring 27 also serves the function of always returning the rocker to itscentral or normal position each time after it has performed its functionas an anti-friction bearing between the two bolsters.

I claim:

In a side bearing for railway cars, the combination with a base platehaving journal bearings therein, 0f a rocker having seated in recessesprovided in the rocker and base plate.

journals positioned in said bearings, a spring extending between saidrocker and base plate, and means for detachably connecting the spring atits ends to the rocker and to the base plate, said means comprising pinsinserted through loops at the ends of said springs, said pins beingre'movably CALVIN B. PATCH.
